FWIW: I think a search will pick up a number of other Z8000 based systems, but Onyx was the first UNIX box.

The very first “Unix at home” system for me was an Onyx 8002 “pedestal” which was connected to three serial terminals: dad, uncle, me :) It was definitely 1980 as it was delivered at home the day of my (unforgettable) 7th birthday. Previously I had only “played” with dad’s TTY into the University systems. Ended up being taught C instead of riding a bicycle… 

We still have the manuals somewhere but the machine was gone when the Avioon came in. No idea where it ended, sadly.
